  • Patent number: 9285024
    Abstract: A torque transmission device comprising a torque converter disposed in a drive train of a motor vehicle, in particular a hydrodynamic torque converter or a fluid clutch, wherein the converter or the fluid clutch comprises a turbine shell and a pump shell which can be coupled through a pump clutch and at least one pump damper with a converter cover, and comprising at least one converter damper and at least one converter lock up clutch.

  • Patent number: 8800731
    Abstract: A centrifugal pendulum in a torsional vibration damper of a drive train of a motor vehicle with a pendulum flange rotating about a rotation axis and several pendulum masses distributed over the circumference, disposed on the latter in a manner capable of swinging. When the internal combustion engine of the drive train induces massive rotational irregularities resulting from high vibration angles in these arrangements, the pendulum masses can be deflected more strongly relative to the pendulum flange and strike the provided swing motion limits. To prevent hard hits of the pendulum masses on the pendulum flanges, it is proposed to dampen the impact areas by hydraulic means and hence to achieve a soft impact.

  • Patent number: 8479901
    Abstract: A hydrodynamic torque converter with an impeller connected on the drive side arranged in housing and a turbine driven by the latter, connected with the driven side of the torque converter, with a turbine damper actively disposed between the turbine and driven side. To improve the vibration damping on the driven side of the torque converter, the turbine damper with a first damper part is formed out of an input part connected with the turbine and an intermediate flange, limited and rotatable opposite and against the action of at least a first energy accumulator and a second damper part with the intermediate flange and an output part limited and rotatable oppositely and against the action of at least a second energy accumulator. An adaptive-speed vibration absorber is arranged on the intermediate flange.

  • Patent number: 7992694
    Abstract: A method and a sealing system for sealing the space between a piston and the hub of a torque converter lockup clutch is provided. According to the method and the sealing system, the seal is pretensioned with its cylindrical surface facing the piston bore. In an embodiment of the invention, the first seal is fastened by a second seal. The invention allows minimization of oil leakage flow and at the same time to linearize its dependency on the differential pressure. Spontaneous sealing may be reduced, thereby directly correlating the contact pressure of the piston—and thus the torque of the torque converter lockup clutch—with differential pressure and eventually allowing for smoother travel.
